Fe danger exists in possible cavitation damages to the baffle blocks or chute blocks. In case of a sloping channel when the stilling action takes place in both the sloping and the horizontal apron, chute Webnappe. The underwater vortex formed by the submerged hydraulic jump is called a “hydraulic” by many kayakers and canoers. Case C, the most dangerous condition, is called a drowning machine because the rotating vortex can easily trap victims by forcing them downward at the overflow and keeping them circulating, first by downstream- shark vacuum navigator professional lift away

A hydraulic jump is a phenomenon in the science of hydraulics which is frequently observed in open channel flow such as rivers and spillways. When liquid at high velocity discharges into a zone of lower velocity, a rather abrupt rise occurs in the liquid surface. The rapidly flowing liquid is abruptly slowed … See more Hydraulic jumps can be seen in both a stationary form, which is known as a "hydraulic jump", and a dynamic or moving form, which is known as a positive surge or "hydraulic jump in translation". They can be described using … See more In spite of the apparent complexity of the flow transition, application of simple analytic tools to a two dimensional analysis is effective … See more Industrial The hydraulic jump is the most commonly used choice of design engineers for energy dissipation below spillways and outlets.
